INTRODUCTION
A robot can be defined as a mechanical device that is capable of performing a variety of tasks
on command or according to instructions programmed in advance. Engineers design robots to
perform complex tasks more easily and with greater accuracy.
•Robot is a system that contains sensors, control systems, manipulators, power supplies
and software all working together to perform a task. Designing, building, programming, and
testing a robots is a combination of physics, mechanical engineering, electrical engineering,
structural engineering, mathematics and computing.
•A robot has these essential characteristics:
•Sensing : Giving your robot sensors: light sensors (eyes), touch and pressure sensors
(hands), chemical sensors (nose), hearing and sonar sensors (ears), and taste sensors
(tongue) will give your robot awareness of its environment.
•Movement: A robot needs to be able to move around its environment. Whether rolling on
wheels, walking on legs or propelling by thrusters a robot needs to be able to move.
•Energy : A robot needs to be able to power itself. A robot might be solar powered,
electrically-powered, battery powered. How your robot gets its energy will depend on what it
needs to do.
